Maybe a little more background would clarify my problem. I'll actually be looking to play a dozen or so pure tones continuously for an unspecified amount of time, then as quickly as possible turn them all off and turn on another set of a dozen or so pure tones that again play continuously for an unspecified amount of time. I can see that for each tone I can set up a player, cue the tone, and set eos_action for that player to 'loop', then once all the players are initialized, tell each to play, but it strikes me that with increasing numbers of players I'll soon be able to notice the difference in start time between the first tone and the last tone, and a similar differences during the transition to the second set of tones. I was hoping that by simply getting the aggregate waveforms I would only have to deal with 2 players, one for each tone set.
